How can a gene that contains introns be made shorter for genetic engineering purposes? What does it use and how does it use it?

reverse transcriptase to reconstruct the gene from its mRNA

Explanation:

Genetic engineering may be defined as the process of using the recombinant DNA (rDNA) technology in order to alter the genetic makeup of the organism. It is also called as the genetic modifications. It uses the science of biotechnology to modify and manipulate the genes of an organism.

A gene containing introns can be made shorter and still remain functional for the genetic engineering purposes by using the reverse transcriptase for reconstructing the gene from the mRNA.

It uses the reverse transcriptase of the mRNA.
